4# out the sub name, but also that that interface does not interfere with
5# prototypes, the way it did before 5.15.4.

69# This is a test for AUTOLOAD implemented as an XSUB.
70# It tests that $AUTOLOAD is set correctly, including the
71# case of inheritance.
72#
73# Rationale: Due to change ed850460, $AUTOLOAD is not currently set
74# for XSUB AUTOLOADs at all. Instead, as of adb5a9ae the PV of the
75# AUTOLOAD XSUB is set to the name of the method. We cruelly test it
76# regardless.
